JOHN STERNAD, OF JERSEY CITY, NEW JERSEY.

CHAIR FOR CLEANING WINDOWS.

Application filed October 29, 1915.

To all whom it may concern:

Be it known that I, JOHN STERNAD, a c1t1- zen of the United States, anda resident of Jersey City, in the county of Hudson and State of NewJersey, have invented a new and Improved Chair for Cleaning V111- dows,of which the following is a full, clear, and exact description.

My invention relates to chairs for cleaning windows, and an objectthereof is to provide a simple, inexpensive and convenient chair wherebywindow cleaning is rendered safe.

Another object of the invention is to pr0- vide a chair for windowcleaning which can be collapsed so that the same may be stored in acomparatively small space.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a fragmentary, perspective view of a building to the windowof which my chair is secured; Fig. 2 is a plan view of the seat sectionand the support therefor detached from the seat and shown collapsed;

and Fig. 3 is a section on line 33,' Fig. 1.

Referring to the drawings, 4 is a seat section in the shape of arectangular board. Rows of U-shaped staples 5 are secured to theunderside of the board. Each row straddles a bar 6 of a seat support 7.An upwardly extending arm 8 is formed at the outer end of each bar bybending a portion of the arm up. The ends of said arms are spaced by arod 9 pivotally connected to the arms, whereby the bars can be swung, asshown in Fig. 2. The inner end of each bar is preferably provided withan extension 10 having a hook end 11 for engaging a window frameinteriorly.

The extensions are secured to the corresponding bar 6 by bolts 12adapted to pass through a set of registering holes 13. This adapts thechair for walls of different thicknesses. /Vhen the window frame has nointerior molding to be engaged by the hooked Specification of LettersPatent.

Serial No. 58,528.

1 ends 11, a bar 14 may be placed transversely of the window and engagedby the hooked ends, as illustrated in Fig. 1. Each of the bars 6 isprovided with a loop 15 forming a brace for engaging the wall below thewindow and maintaining the seat 4; substantially horizontal.

To strengthen the chair back and to pro vide side guards, chains 16 aresecured to the eyelets 17 of the rivets which connect the rod 9 to thearms. A link of said chains is engaged to hooks 18 provided on theextensions 10. It will be noted that when the chair is not in use, thesupport 7 formed by bars 6, arms 8 and braces 15 can be folded as shownin Fig. 2, so that the chair can be stored in a narrow space.

IVhen the chair is to be placed in position for cleaning a window, asshown in Fig. 1, the bars 6 are unfolded and the hooked ends 11 are madeto grip the window frame interiorly with the braces 15 in engagementwith the outer surface of the building Wall. The seat 4: is then placedon the bars. The engagement of the staples 5 will prevent any relativemovement of the bars. A person occupying the chair, therefore, will beperfectly safe, for the arms 8 of the bars 6 and the rod 9 form a backfor the chair against which the person may safely lean. A protectingbelt may be secured to the eyelets 17 to encompass a person occupyingthe seat.

I claim:

A chair for window cleaning comprising JOHN STERNAD.
